Oil conduit mechanism for spindle head of five axis machine tool

Abstract

An oil conduit mechanism for spindle head of five-axis machine tool integrates cutting liquid conduit, lubricating oil conduit and braking oil conduit within the spindle head. Those conduits comprises ducts to guide cutting liquid, braking oil and lubricating oil to the processing location for cooling and lubrication. The oil conduit mechanism further comprises a lubricating oil recycling conduit to recycle the lubricating oil for repeated use.

I claim: 
     
       1. An oil conduit mechanism for spindle head of five-axis machine tool, comprising a spindle cutting liquid conduit comprising an oil duct within the spindle; a nozzle arranged at one end of the oil duct and spraying cutting liquid during the processing performed by the spindle;   a braking oil conduit comprising a B-axis braking oil duct within the spindle head, and a C-axis braking oil duct within the spindle head; one distal end of the B-axis braking oil duct connected to a B-axis braking system, one distal end of the C-axis braking oil duct connected to a C-axis braking system; whereby the B-axis transmission means and the C-axis transmission means of the spindle can be braked at any time;   a spindle lubricating oil conduit comprises an oil duct within the spindle head; one end of the oil duct connected to a plurality of ducts through a dispenser; the plurality of ducts connected to gears and bearings within the spindle head such that lubricating oil can be instilled to the gears and bearings through the plurality of ducts.   
     
     
       2. The oil conduit mechanism for spindle head of five-axis machine tool as in claim 1, further comprising a braking oil recycling conduit having an oil extraction duct within the spindle head, the oil extraction duct having an oil inlet at a bottom side of the spindle head through which the lubricating oil is extracted into the braking oil recycling conduit. 
     
     
       3. The oil conduit mechanism for spindle head of five-axis machine tool as in claim 2, wherein the bottom side of the spindle head is an inclined surface and the oil inlet is located at the lowest end of the bottom side.
